Hi, Saw a fellow birder with the EF300mm F2.8L IS II + 2xIII setup and I want to know how sharp the image will be with this setup. I ask him to let me try to take a shot with my 7D2. I quickly point at the Kingfisher on top of the tree and take a shot at wide open (F5.6)... The AF is still very fast with this setup. When I open the image in LR... WOW... very sharp at 100% crop even without any additional sharpening... just the default LR sharpening.

EF300mm F2.8 IS II + 2xIII F5.6 on 7D2.

Have a nice day.

PS: "We are the EF 300mm F2.8L IS II. Open your wallet and surrender your $$. We will add superior image quality to your images. You'll never look back. Resistance is futile.”

It is significantly faster, more accurate and consistent in focusing than my 5D3.
